I mostly like to print colourful stuff.

I 3D print more for utilitarian purposes.

ASA is awesome and I think having it available in the space is beneficial for a variety of use cases. Pla+ is kind of gross, usually more brittle and moisture absorbing than the non + varieties. Abs GF is good fun and really rigid, good for engineering parts. I don’t print Petg or pla at home, so voting for those because rainbows are cool

want colours for multi colour prints and ASA for printing stuff to go in cars

Also Nylon

Largely do utilitarian prints. I feel we have enough colours now! I find PLA too brittle for utilitarian projects.

Black/white are great, I like at least one accent colour for text/symbols - not really fussed which colour

Black and White are Core. Grey is nice to have Util. Red is the Artifactory Colour and probably the most useful accent colour.

Agree with other comments. Red is also probably the easiest to contrast/see against black, white and grey.

White is cosmetically utilitarian but structurally quite bad due to the titanium dioxide pigment. Would recommend “natural” in its place. Red is a good accent colour. Black and grey are my main primary colours

pretty much just what everyone else said

Grey tends to be the most used utility colour for me as it is neutral. The accent colour shouldn't be too bright, like a dark blue probably.
